Destruction Efficiency in California 2026: Latest Updates, Pros, Cons & How EES Helps Industries Stay Compliant
Destruction efficiency is becoming an increasingly important performance metric for California facilities that use thermal oxidizers, regenerative thermal oxidizers (RTOs), flares, vapor-control systems, and other air-pollution control equipment to reduce VOC and other organic emissions.
In simple terms, destruction efficiency measures how much of a pollutant entering a control device is actually destroyed before the treated gas is released. A commonly used calculation is:
But achieving a high percentage during one test is not necessarily the same as maintaining compliant performance during everyday operation.
California’s 2026 regulatory environment continues to emphasize emission reductions, monitoring, source testing, toxic-air-contaminant controls, and reliable emissions data. South Coast AQMD’s 2026 rule calendar contains more than two dozen planned rule amendments and adoptions addressing particulate matter, toxic air contaminants, monitoring, New Source Review, and other air-quality objectives.
For facilities using thermal oxidation or other control technologies, that creates a growing need for accurate destruction-efficiency testing and defensible compliance documentation.
Energy Environmental Solutions, Inc. (EES) helps industries with Destruction Efficiency Testing, VOC Testing, RTO Testing, Thermal Oxidizer Testing, Source & Stack Testing, CEMS, RATA, CGA, Compliance Test Protocol Development, Engineering Studies, QA/QC, and Regulatory Reporting.
What Is Destruction Efficiency?
Destruction efficiency, often called Destruction Removal Efficiency (DRE), describes the percentage of a pollutant that a control device removes through destruction.
For example, if a control device receives 100 pounds of VOCs and only 1 pound remains in the outlet gas, the calculated destruction efficiency would be approximately 99%.
This measurement is particularly important for equipment such as:
Regenerative Thermal Oxidizers (RTOs)
Thermal oxidizers
Catalytic oxidizers
Afterburners
Flares
VOC control systems
Certain combustion-based control devices
However, destruction efficiency is not the same as capture efficiency.
A facility can have an excellent control device but still release pollutants if the process exhaust is not effectively captured and routed to the control equipment.
That is why compliance evaluations may need to consider capture efficiency + control/destruction efficiency + operating conditions + actual emissions.
Is Destruction Efficiency Testing Compulsory in California?
There is an important distinction.
California does not have one universal destruction-efficiency testing requirement that applies identically to every industrial facility.
Whether a facility must demonstrate destruction efficiency depends on factors including:
Facility location
Local Air District
Air permit
Applicable regulation
Source category
Pollutant
Control technology
Required control efficiency
Federal requirements
State requirements
Permit-specific testing conditions
A current South Coast AQMD emissions-reporting guideline specifically instructs facilities using thermal oxidation to use site-specific destruction-efficiency test results, the applicable permit, or the applicable rule limit when determining vapor-destruction efficiency.
This is an important compliance message:
Don’t assume your facility’s required destruction efficiency—verify it from the applicable permit and regulation.
Latest California Updates in 2026
1. California Continues Strengthening Air-Quality Controls
South Coast AQMD’s 2026 rulemaking program includes more than two dozen planned rule amendments and adoptions.
The agency’s priorities include:
PM reduction
Toxic-air-contaminant controls
Updated toxic-air-contaminant lists
New Source Review
Monitoring requirements
Community emission-reduction objectives
The agency says these activities support the 2016 and 2022 Air Quality Management Plans, 2024 PM Plan, federal and state air-quality standards, and AB 617 Community Emission Reduction Plans.
For facilities using VOC destruction systems, this reinforces the importance of having reliable performance data.
2. Thermal Oxidation Remains an Important Control Technology
South Coast AQMD continues to evaluate thermal oxidation as an emissions-control option.
A March 2026 South Coast AQMD staff report evaluating aerospace coating controls recognized that thermal oxidizers can technically achieve high destruction efficiencies for certain VOC and toxic compounds. However, the agency also identified limitations for some chlorinated and fluorinated compounds because thermal oxidation can produce HCl and HF, requiring additional controls such as scrubbers.
The lesson for industry is important:
A high destruction-efficiency percentage does not automatically mean a control technology is appropriate for every pollutant.
The entire emissions profile must be evaluated.
3. Regulators Are Looking Beyond a Single Performance Number
South Coast AQMD’s 2026 activities demonstrate a broader focus on monitoring, toxic air contaminants, particulate matter, and emissions data rather than relying on a single compliance measurement.
A control device may destroy VOCs while simultaneously generating other combustion-related pollutants.
South Coast AQMD’s emissions-reporting guidance specifically states that thermal oxidation can generate NOx, SOx, CO, PM, and toxic air contaminants, and encourages operators to use site-specific test results for emissions calculations when available.
Therefore, a strong testing program should evaluate the complete picture.
4. Real-World 2026 Cases Show Why Performance Verification Matters
In June 2026, South Coast AQMD hearing-board documents involving Chiquita Canyon included conditions requiring equipment modifications designed to maintain sufficient flare operation and methane content for destruction efficiency consistent with regulatory requirements.
Earlier 2026 correspondence from South Coast AQMD also discussed the relationship between operating conditions, temperature, equipment design, source-test results, and destruction efficiency at the facility.
Although this example involves landfill-gas combustion rather than a conventional industrial RTO, it illustrates a broader principle:
Regulators can require evidence that operating conditions actually support the required destruction performance.
Why Is Destruction Efficiency Testing Important?
A control device manufacturer’s guarantee may say 98%, 99%, or higher.
But what happens after the equipment has been installed?
What happens when:
VOC loading changes?
Production increases?
Temperature fluctuates?
Ceramic media becomes fouled?
Valves begin leaking?
Airflow changes?
Process chemistry changes?
The burner operates differently?
The capture system develops leaks?
That’s where compliance testing becomes valuable.
Testing converts assumptions into measurable evidence.
Key Factors Affecting Destruction Efficiency
Temperature
Thermal oxidation generally requires sufficient temperature for effective oxidation.
If the temperature falls outside the required operating range, destruction performance may decline.
Residence Time
The contaminated gas needs sufficient time in the appropriate combustion environment.
Insufficient residence time can reduce destruction performance.
Turbulence & Mixing
Effective mixing is essential to expose the pollutant-containing gas to the required oxidation conditions.
VOC Concentration
A control system can perform differently depending on the concentration and composition of the incoming VOC stream.
Equipment Condition
Valves, burners, seals, ceramic media, sensors, ductwork, fans, and controls can all affect system performance.
Capture Efficiency
Even a highly efficient RTO cannot destroy pollutants that never reach it.
This makes capture and destruction efficiency two different but interconnected compliance considerations.
Pros of Destruction Efficiency Testing
1. Demonstrates Control Performance
Testing provides measurable evidence of how effectively the control device is destroying pollutants.
2. Supports Regulatory Compliance
Where required by a permit or regulation, test results can support compliance demonstrations.
3. Identifies Problems Early
Testing may reveal declining control efficiency before the problem becomes a larger compliance issue.
4. Supports Permit Applications
Reliable test data can be useful for permit modifications, renewals, and engineering evaluations.
5. Provides Site-Specific Data
South Coast AQMD specifically encourages the use of site-specific destruction-efficiency test results where available for emissions calculations.
6. Improves Operational Understanding
Testing can help facility engineers understand how production conditions affect control-device performance.
Cons & Challenges of Destruction Efficiency Testing
Professional testing also has challenges.
Testing Costs
Specialized source-testing equipment, qualified personnel, laboratory analysis, and reporting can increase project costs.
Production Coordination
Testing may need to occur under representative operating conditions, requiring coordination with production.
Complex Sampling
Some control-efficiency tests require simultaneous measurements at the inlet and outlet.
Variable VOC Streams
Changing process chemistry can make it difficult to establish representative testing conditions.
Secondary Pollutants
Thermal oxidation can create additional pollutants such as NOx, CO, SOx, PM, and certain toxic or acidic compounds, depending on the material being treated.
Documentation Requirements
A technically correct test can still create compliance problems if the supporting protocol, calibration, operating-condition records, calculations, or report are incomplete.
Destruction Efficiency vs. Removal Efficiency vs. Capture Efficiency
These terms are often confused.
Term
What It Measures
Destruction Efficiency
Percentage of pollutant destroyed by the control device
Removal Efficiency
Percentage of pollutant removed from the treated stream; the exact meaning depends on the control process
Capture Efficiency
Percentage of process emissions successfully captured and routed to the control device
Overall Control Efficiency
Combined effect of capture and control/destruction
A facility should understand exactly which metric its permit or regulation requires.

Why Choose EES?
When a regulator asks:
“How do you know your control device is achieving the required efficiency?”
A manufacturer’s brochure isn’t always enough.
You need credible, documented, site-specific evidence when your permit or regulation requires it.
The 2026 Compliance Message for California Industry
California’s 2026 regulatory activity shows that air-quality management is continuing to focus on emission reductions, monitoring, toxic-air contaminants, particulate matter, and community exposure.
At the same time, regulators continue to use site-specific data and permit conditions to evaluate whether emission-control equipment is achieving required performance. South Coast AQMD’s current emissions guidance specifically points to site-specific destruction-efficiency testing, permit requirements, or applicable rule limits when determining destruction efficiency for certain thermal-oxidation applications.
That makes proactive testing a smart compliance strategy.
Don’t wait until an underperforming control device becomes a regulatory problem.
Ask:
Is your VOC control efficiency still meeting your permit requirement?
Are your inlet and outlet measurements defensible?
Are your operating conditions properly documented?
Has your control device been tested under representative conditions?
Is your current test protocol aligned with your permit?
If you don’t know the answer, it may be time for a compliance review.

Why Visible Emissions Evaluation Services Are Critical in California — And How Energy Environmental Solutions, Inc. Helps Industries Stay Compliant
California continues to set the benchmark for air quality regulations in the United States. As environmental agencies strengthen enforcement of emissions standards and increase oversight of industrial operations, Visible Emissions (Opacity) Evaluation Services have become a vital component of environmental compliance programs.
Visible emissions are often one of the first indicators of combustion inefficiencies, pollution control equipment failures, or excessive particulate emissions. Many industrial facilities are required by permit conditions or regulatory rules to perform Visible Emissions Evaluations (VEE) using EPA-approved methods to demonstrate compliance.
At Energy Environmental Solutions, Inc. (EES), we provide professional Visible Emissions Evaluation Services, source testing, engineering support, and regulatory reporting to help industries meet EPA, CARB, and California Air District requirements with confidence.
What Is Visible Emissions Evaluation?
Visible Emissions Evaluation is the observation and documentation of emissions released from industrial stacks, vents, or process equipment to determine whether opacity levels comply with applicable regulations.
Evaluations are commonly performed using EPA Method 9 or EPA Method 22, depending on permit requirements and emission sources.
Visible emissions testing typically includes:
Stack Opacity Evaluation
Fugitive Emissions Observation
Combustion Equipment Evaluation
Particulate Emission Observation
Process Equipment Monitoring
EPA Method 9 Certified Observations
EPA Method 22 Observations
QA/QC Documentation
Compliance Reporting
These evaluations help facilities identify operational issues before they become compliance violations.
Why Are Visible Emissions Evaluation Services Compulsory in California?
California Air Districts require many industrial facilities to demonstrate that emissions remain below allowable opacity limits. Excessive visible emissions may indicate poor combustion, inadequate pollution control, excessive particulate emissions, or equipment malfunction.
Routine evaluations help facilities verify that pollution control systems continue operating effectively while supporting permit compliance.
Latest Regulatory News & Updates
